Bug#490409: xen-3: diff for NMU version 3.2.1-2.1
tags 490409 + patch thanks Hi, The following is the diff for my xen-3 3.2.1-2.1 NMU. It incorporates three patches from upstream and aims to fix CVE-2008-2004 aka #490409. It is not yet tested much, I would appreciate if interested parties could give it a try. I'll upload in due course. Kind regards T. diff -u xen-3-3.2.1/debian/control.md5sum xen-3-3.2.1/debian/control.md5sum ---

Stubdom and blktap
Recently we had a try of stubdom, whose general status is good. One issue we found is with aio/sync blktap as backend, disk performance is obviously slower, and there are some IDE kernel error messages (like irq timeout) at boot time. Another issue (not stubdom specific) comes from blktap''s support for QCOW image which is based on a backing file. We never tried this configure

[PATCH] Blktap: Userspace file-based image support. (RFC)
Attached to this email is a patch containing the (new and improved) blktap Linux driver and associated userspace tools for Xen. In addition to being more flavourful, containing half the fat, and removing stains twice as well as the old driver, this stuff adds a userspace block backend and let you use raw (without loopback), qcow, and vmdk-based image files for your domUs. There''s also a

[PATCH] virtio: Complete feature negotation before updating status
From: Mark McLoughlin <markmc at redhat.com> lguest (in rusty's use-tun-ringfd patch) assumes that the guest has updated its feature bits before setting its status to VIRTIO_CONFIG_S_DRIVER_OK.

compression method for qcow2?
I found guestfs_compress_out do the compression to gzip, bzip2, compress...etc. I want to compress qcow2, and I found details about qcow2 compression in https://people.gnome.org/~markmc/qcow-image-format.html The QCOW format supports compression by allowing each cluster to be > independently compressed with zlib. Can I do that with guestfs_compress_out?
